VEHICLE-SPRING.

Specification of Letters Patent.

Application filed November 11, 1908.

Patented May 31, 1910.

Serial No. 462,078.

To all whom it may concern:

Be it known that I, HENRY WALLACE SMITH, a citizen of the United States,residing at Canton, in the county of Stark and State of Ohio, haveinvented a new and useful Improvement in Vehicle-Springs, of which thefollowing is a specification.

This invention relates to a vehicle spring, and the object of theinvention is a spring which will cause the vehicle body to ride aseasily with a light load as with a heavy one and which will also relieveboth the spring and the vehicle body of the efiects of sudden jars, suchas might be caused by a wheel dropping into a rut, or hollow, this lastadvantage being especially secured by a novel construction of the endsof the spring, with means for securing the spring, so as to leave itsextreme ends free.

In the accompanying drawings :Figure l is a side elevation of thepreferred form of my spring. Fig. 2 is a transverse section takenthrough the spring, on the line 22 of Fig. 1.

In carrying out the invention, I construct the spring of upper and lowermain springs, supplemental outside springs and supplemental insidesprings.

In these drawings, 1 and 2 represent respectively the upper and lowermain springs, the said springs inclosing an oval space between them, theend portions of said springs being bent in the form of scrolls as shownat 3, the scrolls of the main spring 1 being slightly larger than thoseof the spring 2, and the ends of the scrolls are connected by rigid bars1, said bars inclining downwardly, and outwardly with respect to thespace inclosed within the body portions of the springs. These springscome in contact adjacent said connecting bars, but their extreme endportions which are formed by the scrolls 3 are free to give in avertical direction, the bars a not only securing the end portions of thescrolls together, but by their angle of inclination hold the entirespring rigid and free from longitudinal movement. Each of the mainsprings is strengthened and braced by an exterior supplemental spring 5,said springs 5 being fitted to the outer faces of the springs l and 2,respectively. Within the space inclosed by said springs 1 and-2 I placeinterior supplemental springs or leaves 6, which bear upon the mainsprings at all times. It will be obvious that only two interior springsmay be employed one in cooperation with each of the main springs, orthere may be several of the interior springs to each main spring.

Suitable bolts 7 with the usual nuts upon them hold each set, upper andlower, of springs in their proper relation to each other.

By means of a spring constructed as above described, the strength of thespring is equalized as the load increases, and the vehicle will ride aseasily with a light load supported only by the main springs as with aheavy load, when all of the springs are sustaining by their combinedstrength the weight placed upon them.

What I claim is 1. A vehicle spring consisting of upper and lower mainsprings, the upper spring having its end portions resting upon the endportions of the lower spring, the end portion of each spring being bentto form a scroll, said scrolls being oppositely formed, rigid inclinedbars connecting the ends of adjacent scrolls, interior springs bearingon the main springs throughout their body portions, and means forsecuring said interior springs in their normal position with respect tothe main springs.

52. A vehicle spring comprising upper and lower main springs, the endsof said springs being bent to form upwardly and downwardly extendingscrolls, respectively, the scrolls of the upper spring being larger thanthose of the lower spring, rigid bars inclining out of theperpendicular, said bars connecting the ends of the upper scrolls to theends of the lower scrolls, exterior supplemental springs, and interiorsupplemental springs arranged substantially as and for the purposedescribed.
